Cache owners can include basic information about the location on the cache page, even if it is a commercial location. Event caches, like other geocaches, cannot be published if they do not meet the commercial cache guideline.

It's still OK to include the venue's name for an event. Just no links or endorsements, as has always been the case.

Gat R Done, would you and MN: Fruitcake please elaborate on what an "endorsement" is for us party planners.

Statements like "Best Pizza....", "Best price...", "service is great here......", My favorite......", etc. would be endorsements.

What's the difference between stating the name McDonald's and the use of the Golden Arches? They both advertise the commercial business.

The explanation in that old forum just creates confusion and contradiction...

Assuming we're still discussing events vs. other caches:

The purpose of stating McDonalds for an event page is so that people know where the event is. In some instances the coordinates are not as useful for restaurants (ie. those in a mall etc). Some latitude is allowed for events to allow you to list the venue for informational purposes. To list the logo doesn't serve this purpose in the same fashion though - the logo (other than through a very indirect way) doesn't tell people where the event is like the name and/or address.
